So sorry for this miserable situation. I would assume she had far less than ideal accomodations while missing. While BPs roaming their enclosure might BE hungry, that
behavior usually means they're also stressed...in any event, BPs are usually hesitant to accept food when they're out in the open like that. They are ambush-predators
that prefer to grab prey as it cluelessly passes by their hide, so watch for your snake to be peeking out of her hide at night...maybe let a couple nights like that go by for
best acceptance of prey. Until that happens try not to worry & let her relax...maybe cover part of her cage with a towel or paper to help things seem back to normal. Try not to worry about her not eating for 10+ days...that's something BPs are quite well adapted to. With any luck, she'll calm down in another week or so.
